Lindsay Lohan refused to kiss Charlie Sheen while filming “Scary Movie 5,” because she didn’t know where his mouth had been.

Right — that Lindsay Lohan.

Sources close to Lohan told TMZ she was supposed to kiss Sheen three times during their bedroom scene, but refused because of Sheen’s wild past.

Yeah, I’ll give you a second to stop laughing …

It’s unclear what Lohan was paranoid about, though both actors had to sign releases that they didn’t have cold sores.

Apparently the release didn’t cover cooties.

Lohan’s is telling friends she warned producers ahead of time she had issues with kissing Sheen, who has had considerable dental work done in the last couple years, according to TMZ. They still didn’t change the script until it was time to shoot the scene. They supposedly used a body double for some of the kissing parts with moderate success, then decided to write out the tonsil hockey entirely.

Sources told TMZ sheen was totally cool about the whole thing and never voiced any concerns with the rewrite or Lohan’s objections. In fact, then he went and gave her 100,000 to help pay off her taxes.

Imagine how much he would’ve given her if she didn’t pretty much tell him he was disgusting.

WASHINGTON – Hillary Clinton challenged Congress on Thursday to combat fake and misleading news on social media, using a post-election appearance to tackle an issue that gripped her presidential campaign and culminated with a shooting incident Sunday in Northwest Washington.
